To aZZ wiwmz't mag concern:

Be it known that CHARLES C. ELLIs, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, has invented certain new and useful Improvements inAmalgamating Apparatus, of which the following is a specification.

This invention relates to improvements in amalgamators particularlydesigned for the amalgamation of gold and silver ores.

The primary object of the invention is to provide an amalgamating table,which will more effectively amalgamate the ores than apparatusheretofore used.

With the foregoing object outlined and with other objects in view, theinvention consists in the novel features hereinafter described indetail, illustrated in the accompanying drawings, and more particularlypointed out in the appended claims.

Referring to the drawings Fig. 1 is a perspective view of my improvedapparatus.

Fig. 2 is a vertical sectional view of the same.

In the drawings, 1 designates a standard or column having a base 2 thatis designed to be secured to any suitable support.

The upper end of the column is provided with a stud 3 which is pivotallysecured by means of a bolt and nut 4, to the bifurcated end 5 of a tablesupport 6. On this support is rotatably mounted an amalgamating table 7and a ball race and bearings 8 is located between the periphery of thesupport and said table to ensure easy running. A pin 9 on the supportenters an aperture in the table to prevent the table from sliding offthe support when said support is tilted, as shown in Fig. 2.

The support carries a plurality of bearings 10 in which is rotatablymounted a shaft 11 having a fixed bevel gear 12 that meshes with a largebevel gear 13 secured to the underside of the table. The shaft has afixed pulley 14 which may be driven from any suitable power unit. andwhen the shaft 11 is driven the table will be rotated.

Mounted on the top of the table is a circular plate 15 of silveredcopper and this plate has a downwardly projecting stud 16 that entersthe orifice 17 in the table and secures the plate in position.

Extending vertically on opposite sides of the standard 1 are brackets 18having their upper endsprovidedwith bolts and nuts 19.

Posts 20 are adjustably secured to the brackets by means of bolts andnuts 19 which pass through the slots 21 in said posts. Each post carriesa socket 22 through which extends a horizontal arm 23, that carries abrush 24. Screws 25 are employed to lock the arms 23 in adjustedpositions.

A feed launder 26, shown only in Fig. 2, is used to deposit the materialto be amalgamated 'on the plate 15, and a discharge trough 27 isemployed to receive the water and pulp which passes off of the table.

When the bolt and nut connection 4 is loosened, the table and plate 15may be tilted to any angle to regulate the fiow of water, pulverizedore, sand or any other material to be amalgamated, and it will beunderstood that such substances will flow or move by gravity toward theedge of the table that is lowest. As the material flows over the tableor plate, said plate is slowly revolved and this tends to separate thegold or silver from the water and pulp and the valuable substancesadhere to the silvered copper plate while the water and pulp flow offinto the discharge chute 27.

It will'be noted that the material is fed onto the plate at a pointmidway between the brushes 24 and the brushes function to wipe slimesfrom the plate. These brushes may be made of any suitable fibre,bristles or the like and they may be adjusted both vertically andhorizontally to accommodate adjustments of the table.

From the foregoing I believe that the practical operation and advantagesof my apparatus may be clearly understood by those skilled in the art,and I am aware that various modifications may be made in theconstruction disclosed without departing from the spirit of theinvention as set forth in the following claims.

What I claim and desire to secure by Letters Patent is 1. Anamalgamating apparatus including 7 a flat circular plate of silveredcopper adapted to support a coating of amalgam, means for rotating saidplate about an axis inclined to the vertical, means for feeding thematerial to be amalgamated onto the highest portion of said plate, and aplurality of soft brushes positioned above said plate and arranged tocontact with the amalgam carried by the plate and adapted to preventslimes from settling on the amalgam.

2. A method of amalgamating consisting ing a substantially flat silveredcopper amalin feeding the material to be amalgamated gamating laterotatable about an axis in onto a plane silvered copper amal matingclined to t e vertical, a plurality of parallel surface rotating in aninclined p ape, disbrushes resting on the table and arranged'at 5charging the water and p111 from the lowest opposite sides of the tableaxis, and means for 1-5 ed of said table, and simu taneousl brushfeeding the material to be amal mated onto iugfm slimes. from theamalgamating surthe highest side of said plate tween said face andforming grooves in the amalgam brushes, to receive the precious metals.In testimony whereof I afiix my si ature. 10 3.
